| Q. LED Projector,Long Life Technology |
- As we all know, the projector bulb is the same as the more expensive consumables, have a certain life, when the light bulb will use a long time aging, replacement projector lamp is the problem the user must take into account, which is compared to machine LCD TV projector a major disadvantage. Over the years, the major projector manufacturers continuing commitment to R & D use longer bulb, through a variety of ECO technology extends bulb life, and even automatically set up for dual bulb projectors, etc. The ultimate aim is to ensure the maximum extension of the user to replace projector bulb cycle.
- LED projection technologies, has opened a new era for the development of the projector. Compared to conventional projectors, projector using LED light source does not need to replace the biggest advantage is that light bulb. At present the traditional LCD, DLP projector bulb life about 1000 to 3000 hours, while the LED projector's lamp life hours or longer in the 10000-20000, the user fully without worrying about the depletion of the projector bulb.
- LED light source using the projector has the following characteristics:
1, long life, almost without regard to the use of time
2, ultra-portable, ultra-quiet, low heat
3, special power, almost without regard to electricity |

| Q. What is DVB-T? |
- Digital signals are routinely transmitted using terrestrial methods. The transmission method has different names in different parts of the world. DVB-T is the name used in Europe and Australia. North American customers receive these signals using a set of standards approved by the Advanced Television Systems Committee (ATSC). In Japan, it is known as Integrated Services Digital Broadcasting–Terrestrial (IDSB-T).
- DVB-T broadcasters transmit data using a compressed digital audio-video stream, with the entire process based on the MPEG-2 standard. These transmissions can include all kinds of digital broadcasting, including HDTV and other high-intensity methods. This is a vast improvement over the old analog signals, which required separate streams of transmission. Oddly enough, some DVB-T transmissions take place over analog networks, with the antennas and receivers getting some helpful technological upgrades along the way.
- It’s not just television sets that can receive signals broadcast using DVB-T. Computers can be the recipients of such signals as well. Computer users must purchase a special adapter in order to receive DVB-T, but the adapter is widely available. DVB-T signals can be received on single computers or on networks, depending on where the adapter is attached.
- DVB-T is not the only DVB out there. The Digital Video Broadcasting Project — a group of nearly 300 broadcasters, network operators, and software makers that since 1993 has designed global open standards for digital television transmissions — has created other formats as well. Also used in Europe are DVB-C and DVB-S. The letters in those acronyms are C for Cable and S for Satellite. Another well-known protocol is Digital Video Broadcasting–Multimedia Home Platform (DVB-MHP). One kind of DVB soon to be getting lots of media attention is Digital Video Broadcasting–Handheld (DVB-H). This is the data transmission method used for mobile TV, which will no doubt be part of the future of broadcasting.

| Q. DLP and LCD Projector Technology Explained |
- Projectors can be broadly catogorised into two technologies, DLP (Digital Light Processing) or LCD (Liquid Crystal Display). This refers to the internal mechanisms that the projector uses to compose the image.
- Until recently, LCD was reserved for less expensive designs while DLP models held the performance edge for high-end projectors. However, recent advances have seen both technologies converge and in most cases there is less of a reason to pick one technology over another.
- LCD technology has improved immensely in the last year or two while DLP models are more competitively priced than ever before. So in short both technologies are now able to offer crisp, clear and vibrant images, the main consideration to make on which projector is right for you is down to the more specific requirements such as brightness, resolution, contrast and connectivity.
- It is worth mentioning though before you read on that despite the advancement in both technologies, LCD and DLP still each have unique advantages over one another, which is why its important to understand what each of the technologies has to offer.

| Q. What is the life expectancy of my DLP lamp? |
- Lamps typically last about 2,000 ~ 3,000 hours when installed in the TV. Keep in mind however that some lamps won't make it all the way to their estimated life spans. If you operate your DLP TV in a warm environment that is not adequately ventilated, or at higher elevations, this can reduce lamp life. Also, failing to keep the air filter clean may reduce lamp life as well. And some lamps will just fail sooner than others; estimating average lamp life is not an exact science.
- Lamp life can be extended slightly by refraining from turning TV on/off as frequently. A power outage will absolutely shorten the life span of the lamp; there are cooling fans that continue to run after you shut off the power, therefore unplugging the TV should be avoided because it would not allow the TV goes through a cool down cycle. DLP lamp is not an ordinary incandescent bulb, but a high-pressure mercury lamp and it gets HOT. Since it's inside the cabinet of your TV the fans are needed for airflow to cool the lamp.
